目的控制骨肿瘤切除骨关节重建术的感染。方法对１１０例四肢恶性骨肿瘤切除骨关节重建术后感染的可能因素进行了分析。结果发现６种术式术后感染率为１１．８％，其中液氮灭活瘤段再植术后感染率最高，达２６％，第二高发者为同种异体骨关节置换术，为１１．１％，其感染主要表现为慢性感染。结论肢体抢救术式、患者免疫功能状态、抗生素的合理预防应用、排异反应及高质量的护理与术后感染的发生密切相关。
Objective To control bone tumor resection for bone and joint reconstruction. Methods 110 cases of malignant bone tumors of the extremities were analyzed for the possible causes of infection after bone and joint reconstruction. The results showed that the postoperative infection rate was 11.8% in 6 types of surgical operations, and the highest infection rate was 26% in the inactivated liquid nitrogen inactivated tumor segments. The second highest incidence was allograft osteoarthrosis 11.1. %, the infection is mainly manifested as chronic infection. Conclusion Limb salvage surgery, patient’s immune function status, reasonable preventive application of antibiotics, rejection and high-quality care are closely related to the occurrence of postoperative infection.
